Zinc Myristate

What is Zinc Myristate?

Zinc myristate is the zinc salt of myristic acid, a saturated fatty acid typically sourced from coconut or palm kernel oils. It appears as a fine white powder and finds common use in color cosmetics, particularly powders, foundations, and pressed products. In formulations, it acts by absorbing moisture to prevent powder clumping, ensuring smooth flow and even distribution during manufacturing and application. As a slip modifier, it reduces friction for effortless gliding on skin. It also adjusts product thickness for optimal stability and user experience, while opacifying to create a uniform, creamy appearance that hides imperfections. Derived through neutralization of myristic acid with zinc oxide or hydroxide, it supports lightweight, buildable coverage in makeup without heaviness.
